At the weekend I was reading a book called Selling to Big Companies (by Jill Konrath). In it, one of her major suggestions is you limit who you market to. Rather than trying to get sales from anywhere, you target two or three industries (or just one if you think it's big enough). This has two advantages: 1/ You spend less money and time promoting your business, because your marketing is far more focused - as opposed to having to do a different campaign for each industry; 2/ You can learn more about one or two industries and therefore be able to talk intelligently with the decision makers in those industries, so will become trusted and respected far quicker than if you are trying to be a "Jack (or Jill) of all trades". What do you think? Do you market to all and sundry, or do you just focus on two or three industries that are most likely to need your product or service? What has been your experience?
